For the remand prison Prague – Ruzyně we installed a filter of mechanical impurities, generator of chlordioxide and a device for water softening.
Ruzyně prisonAccording to the request for a reconstruction of the original central hot water gas boiler room of the prison Ruzyně the heating of hot service water was complemented by the device for dosing of chlordioxide for disinfection of the HSW pipes in the area. Dosing of chlordioxide ensures a maximum possible protection of the water against bacteria.

Chlorine dioxide is, according to the notice of the Ministry of health 293/2006 co. and the notice 409/2005 co., paragraph 14, point „i“, approved way of disinfetcion of both drinkable and hot water.

The generator automatically prepares a solution of chlordioxide of the hydrochloric acid and a sodium chlorite. The solution is then dosed based on the watermeter data, in concetration of 0,2 to 0,6 mg/l.

Dosage within this limit safely secures a disinfection of the pipes, everywhere where the hot water circulates.

We guarantee that while using this technology, water will meet the requirements of the notice 293/2006 co. on the continuously used outlets of the hot water. The notice determines hygienic requirements for drinkable and hot water and the frequency and range of the drinkable water checks.


The chlordioxide generator EuroClean OXCL was placed in the area of exchanger station. On the inlet pipes of cold water we installed an impulse watermeter whish is used for management of the dosing.
